Turnbull says UN climate talks 'not the end of the journey'

PRIME Minister Malcolm Turnbull has left open options to increase Australia's carbon emissions reduction target in two years.

Mr Turnbull and his opposite number Bill Shorten are in Paris for the United Nations climate talks. While the government has promised a 26-28% reduction by 2030, the Prime Minister said ahead of the talks that he wanted a "strong a durable commitment".

He said Paris was "not the end of the journey", while a report in The Australian, quoting unnamed sources indicated he was considering increasing the target in the next two-yearly review.

As hopes of a deal increase, Mr Turnbull said the Paris agreement was only a "step along the way to achieving a net zero-emissions world".

Mr Shorten had last week pledged Labor to a potential 45% reduction by 2030, pursuant to "industry" negotiations, a policy Environment Minister Greg Hunt criticised at the time.

Mr Hunt told ABC a deal would be reached, even if it was not "perfect".
